Induction Sealing Technical Articles

Achieving a Perfect Induction Seal

The process of developing a perfect seal solution includes matching the cap, liner and sealer; setting up an operating window; and establishing testing methods for identifying a good seal. By understanding how to address and control induction sealing variables, companies can achieve a perfect seal every time.

After 18 Pack Expo International Trade Shows Zito has seen many changes in the packaging industry

Bill Zito will be attending his 18th Pack Expo show this year and since the early 1980s a lot has changed in the packaging industry and with induction sealing. We took the opportunity to pose him a few questions on where.

Are two sealing heads better than an "All-in-One?"

When you're sealing a wide range of containers an "All-in-One" sealing head can be ideal. With sealing capabilities ranging from 20mm to 120mm it can be a contract packagers best friend.

Are you maximizing the productivity of your induction cap sealer?

Finding the best cap sealer for your application might not be as simple as you think. With the introduction of several new models over the past few years you have more choices than ever before. And your choices aren't only limited to the cap sealer's power supply and sealing head. New options and features can add value and productivity to your investment.

Cap inspection and foil detection systems boost productivity

Enercon Induction sealers have earned a great reputation for offering tamper evidence, preserving freshness and also preventing leaks.

Cap manufacturers and packagers unite: pressure sensitive liners are on the way out!

Several years ago, Bill Zito wrote about the disadvantages of pressure sensitive liners (PSL). Among the shortcomings were lack of tamper evidence, the inability to be used with liquid products and the absence of any type of moisture and oxygen barrier properties.

Comparing apples to apples is nice, but sometimes you'll find comparing apples to oranges is better

Its obvious that all induction sealers are not created equal. It can also be said the companies selling and manufacturing these systems are not created equal. In fact sometimes its like comparing apples to oranges.

Don't be fooled by kilowatts

There appears to be a misconception in the packaging industry concerning the relationship between the kilowatt ratings of induction sealing systems and sealing capability. While it is true that a higher kilowatt rating means a more powerful system, this doesn't necessarily result in higher sealing rates.

Enercon "Success Guarantee" based on a world of experience

When you request a proposal from Enercon you’re tapping into decades of application expertise. But how can we guarantee your success?

Foil tampering and instill consumer confidence

The 9/11 terrorists attacks on the World Trade Center and the Pentagon have had a dramatic, if subtle, effect on the way products are viewed and packaged.

Future of Induction Sealing: Trends & Developments Report

Sustainability, ease of use, productivity & anti-counterfeiting top the list in this insightful report from Mary Ann Falkman. Discover how material & equipment developments are driving change in the packaging industry. Read more courtesy of Enercon …

How to calculate conveyor speed in feet per minute

Many times packagers are familiar with their bottling requirements in terms of containers per minute (CPM). When Enercon sizes a cap sealing system for an application we rely on the conveyor speed expressed in feet per minute (FPM).

Improve your induction cap sealing IQ

Teachers like to say there’s no such thing as a "dumb" question. And when it comes to induction sealing I’ve heard them all. In this article I’ll answer some of the more common questions.

Inconsistent application torque Equals Inconsistent seals

In order to get a good hermetic seal, it's necessary for the foil innerseal, inside of the cap, to be in contact with the lip of the container and have consistent pressure around the circumference. This is accomplished by applying the cap with the correct application torque.

Induction foil seals for tamper evident packaging

The right inner seal for your container gives consumers confidence in safety and convenience. Inner seals provide tamper evidence and a hermetic barrier. Emerging technological developments include new designs that improve safety from tampering and counterfeiting, new materials to improve barrier properties, and peelable structures that are easy to open for greater consumer convenience.

Induction heat sealing helps in reduction of pack and bottle weight!

For many years now, the milk industry has taken great advantage of foil sealing, which allows them to reduce closure weight, eliminate the tear band, and reduce pack weight.

Induction Sealing Infographics

Use these visual guides to help operators to quickly evaluate an induction seal and set up your operating window.

Induction Sealing Sustainability Benefits

There are many areas that packagers and manufacturers may consider while striving for sustainability. Packaging material reduction, renewable packaging resources, reduced carbon footprint and energy savings are a few of them. Find out the substainablility benefits for including an induction seal.

Is your induction sealer turned on? How do you know?

The potential cost of conveying packages under your induction sealer when it's turned off can be staggering. Consider lost production time & product scrap first, but also consider the risk of unprotected products leaving your facility. It might cost you a distribution channel or a customer. Find out which solution is best for you.

It's not only food that's vulnerable! Personal care products need to take notice

When outgoing Secretary of Health and Human Services, Tommy Thompson, was leaving his cabinet position in the Bush administration, he made a point of informing us that "we're most vulnerable for a terrorist attack against our food chain."

Reducing pack weight with an induction seal

What may surprise even the most experienced packager is that induction seals are being used to reduce pack weight and carbon footprint. The impact of this trend is far reaching and one of the best examples can be found in Europe.

Sealing Flammable Liquids

We are often asked if it is safe to seal flammable liquids, that have extremely low flash points. There appears to be a misconception by the packagers of flammable liquids that the heat generated by the induction sealing process will somehow ignite their product. This confusion is caused by insufficient knowledge of the induction sealing process and the variables involved in determining if a flammable product will ignite.

Super Seal™ Touch is the latest in Enercon's long history of induction innovations

At the recent Pack Expo in Las Vegas, Enercon introduced its latest induction sealing system, the Super Seal™ Touch. It gave me a chance to reminisce about the first induction sealer and how far the industry has come since its inception.

The cheapest system isn’t always the least expensive

Shopping on price can be smart and risky at the same time. In most cases, Enercon is able to meet the needs of even the most budget conscious purchaser.

The Hidden Benefits of Induction Seals

As a packaging professional you recognize that the induction seal is a critical component of your packaging design strategy. It provides your products with tamper evidence, leakage prevention, freshness preservation, shelf-life extension, and theft deterrence.

Tips and Techniques for Testing Induction Seal Leaks

One of the most frequently asked questions we receive is how to test for leaks. Unfortunately, there is not a simple answer to this question. There are no ASTM specifications, or guidelines relating to the testing of induction seals. Everyone seems to do it “their way.”

Why induction sealing is an effective method of tamper-evidence

Induction sealing is a non-contact heating process that accomplishes the hermetic sealing of a container with a closure that includes a heat-sealable foil laminate inside of the closure. When the appropriate type of seal is used, the seal can not be removed without leaving evidence on the lip of the container.

Will a cheaper induction sealer end up costing you more?

While recently surfing the internet, I was amazed to see the number of used induction sealers that were being offered on"used equipment" web sites.
